β-lactamase is an enzyme capable of hydrolyzing β-lactam antibiotics, and its residues in milk are increasingly concerning. The endogenous factors related to β-lactamase residues in milk are associated with the health status of the cows themselves, while exogenous factors mainly involve illegal human addition. The residues of β-lactamase may cause various health risks, including the accumulation of cytotoxic degradation products, the failure of antibiotics, and drug resistance development in humans. Currently, detection methods for β-lactamase residues in milk include microbial methods, iodometry, acidity meter method, instrumental detection method, and rapid detection method, etc., but all these methods have limitations. This article reviews the biological characteristics, sources, and recent research progress on detection methods of β-lactamase in bovine milk. Also discusses the limitations of current detection methods and provides an outlook on future management measures and emerging detection technologies. The aim is to provide scientific references for detection personnel and researchers, ultimately enhancing dairy product safety.
